Head On is an arcade game released in 1979 by Sega. Cars continuously drive forward through rectangular channels in a simple maze. At the four cardinal directions are gaps where a car can change lanes. The goal is to collect dots in the maze while avoiding collisions with the computer-controlled car that is also collecting dots. It's the first maze game where the goal is to eat dots, and Head On is considered a precursor to Namco's 1980 hit Pac-Man.
